EMANE vs NetSim by Tetcos

EMANE has no write-up on Specifiction yet; its figures are above.

NetSim by Tetcos is a packet-level, discrete-event simulator and emulator for wired and wireless communication networks. It models end-to-end 5G and 6G systems with gNB, UE, 5G Core, MIMO, beamforming, network slicing, and configurable propagation. Each 5G stack layer includes C source code that users can modify for custom protocols, while an external Python interface supports automation, AI/ML workflows, and runtime control. Standard and Pro editions interface with Python, MATLAB, SUMO, and Wireshark. The Emulator connects simulations with real hardware and live applications, applying configured delay, loss, and error conditions. NetSim Cyber adds network and attack emulation for power-system cyber-physical testbeds and interfaces with listed power-system tools. Licensing can remain local through on-premises floating deployment, and cloud licensing exchanges only handshake data. NetSim runs on Windows; emulator setup specifies a dedicated Windows 10 or 11 machine.
